Some terminology I’ve seen cause some confusion in the media:
To most people, a “signal” from space implies something intentionally transmitted, like a beacon or a message 👋🏼👽
To an astronomer, it’s *any* radiation we pick up (like a burst of radiation from a star) 🌟

This has come up recently in media discussions of a newly detected #FastRadioBurst — described by astronomers as a “repeating signal” from the distant cosmos. It’s probably just some weird stellar emission process! All “signal” means to us is that we can detect a bit of radiation
Relatedly, to an astronomer, “radiation” usually means electromagnetic radiation, which is visible light, radio waves, gamma rays, or any other kind of light (visible or not) — not just the kind of radiation one gets from dangerous radioactive substances, or nuclear accidents.
